STERILIZING VAPORIZER.

Application filed April 9, 1928, Serial No. 268,680. Renewed March 26, 1929.

The primary purpose and object of my device is to furmsh physicians, hospital attendants, public buildings, operators, home owners, and others with a device to sterilize the air in buildings and elsewhere and make the same palatable, sterile and fit and safe to breathe by releasing within the air of medicated elements from vaporizer in a finely divided state in combination with water vapors so that the medicated elements are held in suspension within the air thereby sterilizing the same.

The invention consists primarily of a body element, electric means for heating the base of the body element and means being provided for dividing the upper portion of the body element into a plurality of compart-- ments, one of which compartments being adapted for the maintaining of water there' in, and another of the compartments being adapted for the retaining of the medicated elements therein, and means being provided for the passing of the water vapors when formed by the application of heat through the chamber containing the medicated elements and the final mixing and releasing of the combined vapors through a common outlet into the air. 7

Means being provided for an easy filling of the various compartments with the respective elements and for the disassembling and the assembling of the completed unit to facilitate the maintaining of the same in a sanitary manner and condition. lurther objects of my new and improved device consist in providing a device of a maximum vaporizing capacity, one that may be easily and quicklyheated and that may be maintained ln a sanita and operating con- 40 dition with little effort, that is neat in appearance and eifieient in its operation. A further object of m new and improved device consists in provi g a sterilizing vaporizer that may be safely used by physicians,

nurses, hospital attendants, home owners and others through the use of which the spreading of contagious diseases may be halted and prevented.

these and'incidental objects in view the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which hereinafter shown with reference to the drawings which accompany and form a part of this specification.

In the drawings:

Fig. 1 is a side elevation of the assembled device.

Fig. 2 is a side elevation, partially in section of the assembled device.

Fig. 3 is a sectional, top, plan View, taken on line 33 of Fig. 2, looking in the direction indicated.

Like reference characters refer to like parts throughout the several views.

I preferably form my device of a body element 1, having an outwardly flaring base 2, disposed thereupon iterminating in the supporting cylindrial bottom 3. A cross diaphragm 4 is disposed at the lower end of the cylindrical portion of the body element, thus forming a compartment 5, disposed below the diaphragm into which the heating element 6 is placed. Electric current for heating the heating element 6 is supplied through the electric conduit 7, through the base or bottom 3, into the device. To prevent the heating of the bottom structure, an insulated material 8 is placed thereupon and upon which the base rests; an upwardly extending boss'9 rests upon the diaphragm 4 into which a central hollow column 10, is secured as by being threaded thereinto; disposed upon the hollow central column 10 is a band 11, which may be threaded intoor made to engage within the top flange 12 of the cup 13. The cup 13 is'disposed about the hollow central column 10 and is secured thereto by any suitable fastening means, as by a pressed fit of the composition as to volatilize at substantially the same temperature as the carrying agent,

as water, disposed within the compartment 16, so that as the vapors pass downward through the central opening 19 of the column 20 the same would enter into the cup 13 and intermingle and mix with the vapors therein developed from the medicated elements. The combined mixed vapors would then pass through the openings 21 disposed through the side walls of the central column 10 and would pass upward therethrough and out into the atmosphere. The carrying agent disposed within the compartment 16 may be placed therein through the filling elbow 22 which is removably secured to the body element 1. A

closure cap 23 closes the same. To afford portability to the device and to facilitate the handling of the same while in a heated condition a handle 24 is disposed upon the outside of the body element and is removably secured thereto, the same being preferably made of an insulated material, as Wood, or

other fibrous material of aslow heating conducting material.

In devices of this kind it is essential that the same be so constructed as .to facilitate the maintaining of the same in a sanitary condition. This is accomplished in my new and improved device'by the ease with which the same may be disassembled. The cup 25 is in threaded relationship with the outer upper surface of the central column 10 and the conical closure 26 rests upon the upper surface of the collar or flange 12 and extends downward therefrom and the flange 27 disposed upon the lower side engages with the outer surface 7 of the body element. The lower end is in threaded engagement with the boss 9 of the diaphragm 4. The removal of the top structure 25, and the conical closure 26 may then be readily removed from position at which time the central column may be unthreaded from the flange 9 and the cu 13 then re moved. The central column eing fixedly secured to the cup may then be removed from the cup, so that each of the associated elements may then be thoroughly cleaned and placed in a sanitary condition.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all comin within the scope' of the claims which fo low.

What I claim is:

1. In a device of the class described, the combination of a body element havin an outwardly extending base disposed on t e lower end of the body element, a diaphragm extendin across the body element at the juncture of the body element and the base, an electric heating element disposed within the base and below the diaphragm, an electric conductor for supplying heatin ,ener to the heating element, an upwar exten boss disposed central of the diaphragm an removably secured thereto, a on disposed the ends of the central column, said cup having an outwardly extending annular top flange adapted to engage with and rest upon the upper end of thebody element, a band disposed about the central column and in registerable alignment with the cup and adapted for engagement with the cup and to 7 form a tight fitting lid therefor, a plurality of openings disposed within the top e and a plurality of hollow columns upwa y extending from the band and extendin therethrough, a conical closure dispose about the central column and resting upon the top flange and adjustable means for maintaining the assembled unit in adjustment and assembled.

2. In a device of the class described, the combination of a body element having a base disposed its lower end and a diaphragm disposed its ends to form two compartments, oneon either side of the diaphragm, a heating element disposed adjacent to and below the diaphragm, means for supplying heat associated with the heat element, a central hollow column upwardly extending from the diaphragm and removably secured thereto, a cup securedto the central column and disposed within the upper compartment of the body element, a closure for the body element and removably secured thereto about the central column which upwardly extends therethrough, intercommunicating passageways disposed between the upper compartments disposed within the body element and means for filling the upper compartment disposed within the body element and for exhausting the vapors developed within the body element and within the cup.

3. In a device of the class describedpthe combination of a body element composed of side walls and a horizontal diaphragm dividing the body element into compartments, one of said compartments having means associated therewith for the application-of heat to the diaphragm and the other of the compartments comprisin a liquid holding well, a second liquid hol ing compartment disposed within one of the compartments of the body element and a third compartment formed by a closure removably secured to the upper end of the body element and intercominunicating passageways connecting the compartments and the exterior through the remeans for supplying heat through the bottom to one of said compartments, a hollow 10 column removably secured tothe bottom of the body element and upwardly extending through the compartments disposed within the body element, and intercommunicating passageways connecting the compartments 15 and the hollow column to the exterior.
